A New Shipborne Microwave Refractometer for Estimating the Evaporation Flux at the Sea Surface

摘要

After a brief description of humidity measurement and a short presentation of methods of microwave refrac- tometry for evaporation flux, a new X-band refractometer system is presented. Based on a new design and a new material for the microwave cavity, it does not need calibration for refractive index variations because of its reduced thermal time constant.
